Sea Pump System
For all ILMOR equipped boats, a check of the raw water pick-up is necessary. Located
beneath the boat, under the water line on the hull is the raw water pick-up. Even when boat-
ing on clean-appearing bodies of water, a check of this pick-up should be done after every
outing to determine if there is any debris. This should be rinsed with fresh water
prior to storage, even of short duration. It will be easier to clean following an outing
than waiting and possibly allowing debris to dry.
Place a flushing device on the raw water pickup on the bottom of the hull. Turn the garden
hose ON and start the engine.
• Cycle engine speed from idle to 2000 rpm in 10-second intervals, allowing the engine
to reach operating temperature. T he engine needs to be at its operating temperature for
fifteen (15) minutes. T he garden hose flow rate may need to be adjusted if engine will not
warm up; it must warm up to open the thermostat, which is required for proper flushing.
If the engine will not warm up, remove thermostat and flush engine with fresh water
for five (5) minutes while cycling the engine speed from idle to 2000 rpm in 10-second
intervals.
• Fresh water boats should be flushed when going to storage or not being used for periods
in excess of one month.
• Salt water boats should be flushed with fresh water after every use. Boat-
in-water flushing can be achieved with a flushing device. The seacock will need to be
closed while supplying fresh water to the inlet of the sea pump and allowing it to circu-
late through the engine. T he engine must reach operating temperature for a minimum
of five (5) minutes to allow the thermostat to open and circulate fresh water.
